Highlights from this day
one unit is 0.01ml. 100 units is 1ml. everything else in this channel follows from that, for what its worth
label the date too. you will not remember which vial is which by week 15
swirl it. do not shake it. the foam is denatured protein and you are not getting it back
anyone else find the 30mg vials harder to get fully dissolved than the small ones
clear or bin it
it should be completely clear with no floaters. cloudy means stop, i think
bacteriostatic water for anything multi-use. sterile water has no preservative in it at all
5mg in 2ml gives 2.5mg/ml, 0.25mg is 10 units. good for a starting dose

right so took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience, i think
read it at eye level
the jewellery scale is a good habit but calibrate it, they drift badly
thats 5mg/ml
sorry to jump in my vial pulled the water in on its own, is that the vacuum or did i do something
nobody here should be telling you a dose. we can check your arithmetic, thats a different thing
whats the smallest volume you would trust yourself to measure on a u100
*Medutest not the other one
is it normal for the cake to look slightly collapsed on one side
pick the volume so your dose is a whole number of units. thats the entire trick
gross powder mass is not net peptide. water and counterion are in that number
you can absolutely just always use 2ml, and honestly most of us should
if i add 2.5ml to a 5mg vial what concentration am i actually at
bac water or sterile water for something im going into weekly for 7 weeks
foam is bad

slightly off topic but my rule is one concentration for everything so i never have to think about it at 7am
the meniscus thing is real. read it at eye level or you are guessing by a unit either way
weigh it first
does benzyl alcohol matter if im finishing the vial in one go
20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
update on the earlier thing i write the mg/ml on the vial with a sharpie the moment i reconstitute it, not advice obviously
update on the earlier thing give it 3 minutes at room temperature before you decide it has not dissolved
bac water
write the date on
does it matter if i inject the bac water straight at the powder

follow up dead space in a standard insulin syringe hub is small but it is not nothing over a month

if the maths gives you 13.7 units, change the volume. do not try to hit 13.7
quick one 15mg in 3ml is 5mg/ml. same numbers as 10 in 2, just more of it

aim the diluent at the glass wall, not at the powder. it goes in gentler

what do you do with the last 15 units when you cant draw them cleanly
gross powder mass is not net peptide. water and counterion are in that number

weighing the vial before you reconstitute is the only way to catch an underfill
